OBJECTIVE: To evaluate the role of brain natriuretic peptide (BNP) in predicting the progression of heart failure (HF) after cardiac resynchronization therapy (CRT). BACKGROUND: It has been shown that BNP predicts the prognosis and can guide the treatment of HF. METHODS: We studied 50 consecutive patients (61+/-10 years, 23 male) with HF (8 with ischaemic cardiomyopathy), NYHA class III, left bundle branch block, left ventricular ejection fraction (LVEF) 91.5 pg/ml had 89% sensitivity, 59% specificity, and negative and positive predictive values of 96% and 33%, respectively, for HF progression after 12 months. CONCLUSIONS: HF patients with high BNP values after 1 month of CRT have worse prognosis during follow-up. Therefore, in these patients other therapeutic options should be considered.
